Answer:

$x = 1 +/- \frac{i\sqrt{10} }{2}$

Step-by-step explanation:

The equation given is:

$2x^2 = 4x - 7\\\\2x^2 - 4x + 7 = 0$

Using quadratic formula:

$x = \frac{-b +/- \sqrt{b^2 - 4ac} }{2a}$

From the question:

a = 2, b = -4, c = 7

Therefore:

$x = \frac{4 +/- \sqrt{(-4)^2 - 4 * 2 * 7} }{2 * 2}\\\\x = \frac{4 +/- \sqrt{(16 - 56)} }{4}\\\\x = \frac{4 +/- \sqrt{-40} }{4}\\$

=> $x = 1 +/- \frac{i\sqrt{10} }{2}$

A company policy requires that for every 30 employees, there must be 3 supervisors. If there are 267 supervisors at the company,

Alexus [3.1K]

267 supervisors will have 2670 employees.

Step-by-step explanation:

Let x be the number of employees.

Given,

3 supervisors = 30 employees

1 supervisor = $\frac{30}{3}$

1 supervisor = 10 employees

As one supervisor has 10 employees, 267 supervisors will have;

x = 267*10

x= 2670 employees

267 supervisors will have 2670 employees.
